PDAC Regression and Intraoperative Surgical Margin With Neoadjuvant TAMP (PRISM-TAMP): A Phase Ib/II Open-Label Trial
University of Vermont
Summary
Pancreatic ductal adenocarcinoma (PDAC) is an aggressive cancer with poor survival outcomes, even when treated with modern chemotherapy and radiation. Patients with borderline resectable PDAC often receive neoadjuvant systemic therapy to improve the likelihood of successful surgical removal of the tumor, but rates of incomplete tumor regression and positive surgical margins remain high. This Phase Ib/II, single-arm study evaluates the safety and feasibility of adding trans-arterial microperfusion (TAMP) delivery of gemcitabine to standard neoadjuvant therapy for patients with borderline resectable PDAC. In this study, patients receive standard systemic chemotherapy with modified FOLFIRINOX followed by stereotactic body radiation therapy (SBRT). After completion of chemoradiation, gemcitabine is delivered directly to the tumor through the arterial blood supply using the RenovoCath® catheter system. Gemcitabine is an FDA-approved chemotherapy drug for pancreatic cancer, and the study is evaluating a novel method of delivering the drug rather than a new medication. The primary objective of the study is to assess the safety and tolerability of neoadjuvant TAMP-delivered gemcitabine in this treatment setting. Secondary objectives include evaluation of surgical margin status and pathologic tumor regression following surgical resection. Exploratory analyses will examine relapse-free survival. Results from this study will help determine whether this locoregional chemotherapy approach can be safely integrated into neoadjuvant treatment strategies for patients with borderline resectable PDAC.
Description
Pancreatic ductal adenocarcinoma (PDAC) remains one of the most lethal malignancies, with low long-term survival rates despite advances in systemic chemotherapy, radiation therapy, and surgical techniques. Surgical resection offers the only potential for cure; however, many patients present with borderline resectable disease, where tumor involvement of adjacent vascular structures increases the risk of incomplete resection and positive surgical margins. Neoadjuvant treatment strategies are commonly used in this population to improve the likelihood of margin-negative (R0) resection, but local d…
